Kua tāruatia ki te papatopenga
-12+x+3x=10
Me tāpiri te 3x ki ngā taha e rua.
-12+4x=10
Pahekotia te x me 3x, ka 4x.
4x=10+12
Me tāpiri te 12 ki ngā taha e rua.
4x=22
Tāpirihia te 10 ki te 12, ka 22.
x=\frac{22}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{11}{2}
Whakahekea te hautanga \frac{22}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
